what do cows eat?

Cows are both wild and domesticated cattle that can be found all around the world. Wild cattle graze on grasses like brome, timothy, orchard grass and wheat grass, and legumes like clover, alfalfa and trefoil. Cows are ruminants, meaning they regurgitate half-digested food and chew it again to extract more nutrition from it. This allows them to survive on even dry grasses that other animals ignore.

Domesticated cows are kept for milk and beef, and can be fed a variety of things depending on where they are raised. Some cows eat grass in a pasture just like their wild cousins, while others are fed a specialized diet of grains, like oats and barley, and grass hay. Beef cows can also be fed soybeans, beet pulp, cracked corn, rolled oats and other food byproducts. These help the cows grow large enough to supply all of the burgers and steaks eaten in the world, while also using up foods that would otherwise go to waste.
